Our 75' 22 has the bilge pump in the cabin sole just as you step into the cabin. It has a hose that run to the starboard side just above the waterline about 3 feet forward of the starboard setee/berth, in fact the hose runs just under the berth.
The sink has a hose going from it under the little 'step' the porta-pottie sits on and the other end is in the little area in front of the v-berth.
Hope that helps.
Jack
